Ah, now I see what you were going for -- it's not
meant for displaying in RunRev.

Unfortunately, that's not as easy to accomplish :
you'll have to parse the content of the field and try
and determine what is a link and what is not.
The problem there is that people may not always
'format' the link in an easily recognisable way.

A few tricky examples:

1) suppose we want to support including an email
address: someone at example.net must become a link,
including the 'mailto:' bit.
If you just check if there's an '@' sign in the word,
what will happen if you encounter a line
  me:secret at ftp.example.net
which would actually denote an ftp-url.

2) some users will copy&paste a URL from their browser
and it will already contain an 'http://' keyword.
Others will just type "check www.example.net"
Have fun prepending the keywords.

Even though you _can_ overcome all these problems, a
far simpler, alternative method is to provide a
separate field "link" and then insert that into the
html code. It will save you a lot of headaches...

Best regards,
